Read the passage and answer the following questions: After attainment of maturity, all sexually reproducing organisms exhibit events and processes that have remarkable fundamental similarity, even though the structures associated with sexual reproduction are indeed very different. The events of sexual reproduction though elaborate and complex, follow a regular sequence. Sexual reproduction is characterised by the fusion (or fertilisation) of the male and female gametes, the formation of zygote and embryogenesis. For convenience these sequential events may be grouped into three distinct stages namely, the pre-fertilisation, fertilisation and the post-fertilisation events.

What is gametogenesis?

Formation of male and female gametes. Formation of Zygote. Formation of embryo. Formation of ovary.

Formation of male and female gametes.

Gametogenesis refers to the process of formation of the two types of gametes – male and female. Gametes are haploid cells.
